Description

Faucet water softener, control valve for faucet water softener and valve assembly for control valve

Technical Field

The utility model relates to a water softening device, in particular to a faucet water softener, wherein the faucet water softener is suitable for softening raw water (or tap water). Further, the faucet water softener is provided and is suitable for being connected with a faucet to soften raw water. The present invention further relates to a control valve for a faucet water softener and a valve assembly for a control valve.

Background

With the increasing improvement of living standard and the increasing emphasis on health, the quality requirement of people on domestic water is higher and higher. However, in many countries, particularly in developing countries, many sources of tap water are relatively hard ground or surface waters that, after being purified and disinfected, are supplied to users for use. Tap water having a relatively high hardness tends to damage the protective layer of the skin, resulting in dry and astringent skin of the user and even skin allergy. In addition, tap water having a high hardness may also affect the cleansing effect of the skin cleansing article and the cosmetic effect of the cosmetics. Therefore, when the tap water having a high hardness is used to wash the face, the user experience is poor. While water having a lower hardness, such as softened water obtained by softening tap water, is milder to the skin of a user due to its low irritation, and is more suitable for use in cleansing the skin and making up and beautifying. For example, when cleaning the face.

However, the softening device, particularly a small softening device for makeup and/or cosmetology, has a limited content of softening resin, and loses its softening effect on raw water or water to be treated after a certain period of use, and thus can be used continuously after being subjected to a regeneration treatment. Some existing small-sized softening devices do not consider the regeneration problem at all, and users have to discard after losing the softening function after using for a period of time. The other part of the existing small softening device realizes the regeneration of the softening device by taking out the softening resin in the softening device and soaking the softening resin in salt solution. The method for realizing the regeneration of the softening device by taking out the softened resin in the softening device and soaking the softened resin in the salt solution needs to disassemble the softening device, and has higher difficulty. In addition, frequent disassembly of the softener also affects the sealing effectiveness and the service life of the softener.

The chinese utility model patent of application number 201620190999.5 discloses a filter core, filter element group spare and have the water treatment ware of washing one's face and rinsing one's mouth of filter element group spare, and wherein the softening filter core of the water treatment ware of washing one's face and rinsing one's mouth that has filter element group spare that this utility model patent discloses can carry out softening treatment to water. However, the utility model does not provide any mechanism for adding a regeneration solution, such as a salt solution, to its softening cartridge. In addition, the softening material of the washing water treater with filter element group spare that this utility model discloses is not separated and is placed, leads to raw water or pending water short and lead to this utility model patent discloses a washing water treater not good to the treatment effect of raw water in the route of flowing through of washing water treater.

Detailed Description

The following description is presented to disclose the utility model so as to enable any person skilled in the art to practice the utility model. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the utility model, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the utility model.

It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for ease of description and simplicity of description, and do not indicate or imply that the referenced devices or components must be in a particular orientation, constructed and operated in a particular orientation, and thus the above terms are not to be construed as limiting the present invention.

It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.

Referring to fig. 1 to 9 of the drawings, a faucet water softener according to an embodiment of the present invention is illustrated, wherein the faucet water softener includes a water treatment device 1 and a first hose 31, wherein one end of the first hose 31 is adapted to communicate with a source of raw water, such as a faucet, and the other end is adapted to communicate with the water treatment device 1, so that the raw water can flow from the source to the water treatment device 1 under the action of water pressure and be softened by the water treatment device 1 to generate softened water. Most of the softened water produced by the existing water softeners is used for bathing, washing clothes and the like, has large volume, is installed and moved less, and the water softeners are generally communicated with a raw water source through hard pipes such as plastic hard pipes and stainless steel pipes. However, the water treatment apparatus 1 of the faucet water softener of the present invention is connected to a raw water source, particularly a faucet, through a hose, the first hose 31, to be more convenient for a user to use in a kitchen or a dressing table or a washbasin (between a dressing room and a restroom) having a limited area. Generally, the area of an operation table and a dressing room near a kitchen sink is limited, and the operation table and the dressing room are connected by using a hard pipe, so that the operation table occupies a larger volume, and the hard pipe cannot be moved, so that inconvenience is brought to the use of the faucet water softener. In particular, many faucets, such as kitchen faucets, have a rotatable spout for ease of use. If the hard pipe connection is used, the water outlet pipe of the tap water faucet cannot rotate. The water treatment device 1 of the tap water softener of the utility model is connected with a raw water source, especially a tap, through a hose, and the first hose 31 does not influence the rotation of the tap (or a water outlet pipe thereof). Furthermore, the use of a hose connection also allows the user to connect the first hose 31 to the faucet and water treatment device 1 and to disconnect the first hose 31 from the faucet and water treatment device 1 without the aid of tools.

It is noted that the faucet water softener of the present invention is designed to be compact for use in kitchens or in dressing tables or hand washing tables (between dressing rooms) where the area is limited. If the total volume of the softening materials of the faucet water softener is too large, the whole water softener is too large and is inconvenient to use in a kitchen or a dressing table or a hand washing table (between a dressing room and a hand washing room) with limited area, and if the total volume of the softening materials is too small, the water softening capacity of the water softener is limited and the water softener loses the water softening capacity in a short time. Accordingly, the total volume of the softening material of the faucet water softener of the present invention is no greater than 2L. Preferably, the total volume of the softening material of the faucet water softener of the present invention is not more than 1.5L.

As shown in fig. 1 to 9 of the drawings, the inner diameter of the first hose 31 of the faucet water softener according to the embodiment of the present invention is set to be not more than 8 mm. The faucet water softener is mainly designed for beauty treatment and the like, and the using amount of soft water is small. If the inner diameter of the first hose 31 is excessively large, the soft water produced by the faucet water softener of the present invention for a short time exceeds the actual demand of the user, and the excess soft water is wasted.
